I totally agree that there should be one consistent logo.I experimented with a few concepts a couple of months back. Never finished it though. I tried to stay close tho the original but create something unique that looks good in high resolution.Here they are:

The first one is inspired by this image. This is not a real concept (I actually don't like it too much) but it was a exercise for my material skills in Blender.

The second one is a serious attempt that stays close tho the original.

This is a vector version of the second concept that can be used for icons. I attached a .ico file of this logo, with images in various resolutions. (Delete the .png from the file name, I wasn't allowed to upload a .ico file)

I like this last one the best, because I think the cross with three beams is a more original shape.

I like these proposals, but I'm wondering whether maybe it wouldn't be better to have a logo that's a bit more distinct from the Theme Hospital logos, to be safe from legal action.

I think a good symbol for CorsixTH would be the six-pointed game piece from your level board game. It's good symbolism, it's unique to CorsixTH, and it brings Theme Hospital to mind without being too similar to the original copyrighted logo. It also works with various sizes, since you can add/subtract detail and secondary items (like the stethoscope, the briefcase, and the car).

Loved the last one. I'm just divided in regards to the black and white square in the background. I'm not sure if it could be improved (IMO) with something else, like the signpost in the game, or be left as a nod (can't remember a better word) to Bullfrog. The black and white background in the game titles was also used in Theme Park and Theme Aquarium.

@Wolter: Wow, cool, thanks!The icons are great! The pawn in the 2D logo is a bit pixelated, but otherwise I prefer it to the 3D logo (I really like the bright green glow of the 2D version).Thanks again.

Does everyone agree on the following points?:- There needs to be a single distinctive official logo for CorsixTH (as stated in the original post of this topic)- The pawn is to be the central symbol of the logo

Yes to both.From your two concepts I like the first, but would like it more if it were nearer to what we have now i.e. a blue background sign with Corsix TH at the top and then the pawn logo inset - see first comment - with the rivets holding it to the post.

I tried some things with the road signs which turned out quite nice. I personally don't really like the colored logo on the sign, the green and blue don't match well enough. But I like the second one. They are too crowded for a logo IMHO, too much elements. I like to see them as logo artwork that can be used for banners ect.

Here they are:

MY FINAL PROPOSAL FOR THE LOGO:I did some minor adjustments to the first concept in my previous post, and I like it really much. I think it should be the future logo. Here are some versions of it:

I don't think I can improve it anymore so this is my final version. I really hope you guys like it... If you have comments, critique's or request just post them, I can't guarantee they will be granted but you can try .I attached the source files and an .ico file that can be used for the game. (I couldn't upload .ico files, so just delete the .png and it should work.)

The source files are too big, should I post them on the googlecode page?
